EXTEfisioN-EDGE Box-FORMING MACHINE.

Specification of Letters Patent;

Patented Mar. 2, 1920.

Application filed May 26, 1917'. Serial No. 171,255.

To all whom itma'y concern.

Be it known that WB,= DALE G. STEELY, FREDERICK W. BLAKE, and GUSTAV A.,Lo- RENT'ZEX, residing, respectii'ely, at Cambridge, Me'dford Hillside, and West Somerville, all in the county of Middlesei: and State of Massachusetts, have invented an Improvement in Extension-Edge Box-Forming Machines, of which the following is a specification.

This invention relates to an edge extension boX forming machine, wherein an otherwise complete box form is provided, with an additional section to'present an edge extension for the ornamental finish, known as an extension-edge box.

The box which this machineis designed to handle, is either as abody or top, completed except as to covering and lining, on any ordinary box machine, and in such complete form delivered to the machine forming the subject matter of the present invention, and ,has applied thereto by the present-machine, a section of greater dimensions thanthose of the box roper, whereby to present a projecting edge surface on the box or cover, or both, for ornamental purposes The present machine involves a revolving arrier with a series of box forms; on each of which there is' to be s'i'icoessive-l'y placed an otherwise complete box. The carrier is given an intermittent movement, and during its periods of rest thebox on a particular form is in alline'inent with section feeder. constructed to automatically deliver to the box a sectionof material to form the projecting ed e portion of the said box The section feeder receives the sections in superimposed relation of pile form, and

40 the operative parts connected with said feeder, automatically apply paste to the lowermost section of the pile, force said section from the pile, deliver it onto the complete box, and in proper relation wthe surface thereof, centering such" section to form an evenly projected edge Beyond the box. Immediately succeeding the placing of the section, as described, a press member operates" to exert pressure on the section,- to mitially' fix the same upon the box, the said box and section, inthe next movement of the carrier, being brought beneath a final press, for the application of sufficient pressure to the section to insure complete adherence thereof to the box.

The present machine, in the preferred form, is illustrated in the accompanying drawings, in which Figure l is a plan view of the machine.

Fig. 2 is a side elevation of the same.

The machine of the present invention is here shown as comprising amain frame including embed-plate Lhavin'g legs 2. In the rear portion of the bed-plate, mounted in suitable bearings, secured to or carried .on said plate, is a shaft 8, on the upper end of which above the bed-plate is fixed, in an desired appropriate manner, a carrier T.

The carrier is preferably of wheel-like structure, having a hub portion secured upon the shaft, and a series of radiatings'pokes supporting a rim 5, at their outer ends. Secured upon the rim are what may be termed tables 6, that is, imperforate metallic block-like members, having a square upper surface, and in all lineal dimensions corresponding to the interior dimensions of thebo'x or'cover' to which the extension edge section is to be applied. The tables 6 are or may be removably secured to the rim 5, in order that'tables of various sizes may be substituted, to accommodate the machine for coiiperation with boxes of different sizes. A series of such tables 6 are arranged on a rim, six such tables being here shown. The tables are arranged with their major dimensions tangentially of the rim, and the width of the rim is preferably materially less than the similar dimension of the table.

For the purposes of the machine, it is important that the carrier be given an intermittent revolving motion, having periods of rest during which the various operations of the machine, with respect to the extension edge forming section, are carried out. Itis, therefore, important that the movement of the carrier be more or less accurately timed, and that the respective periods of rest be absolutely uniform and regular, in order that each table with its carried boxes or top may be successively operated upon by the various mechanims to be described.

Movement and control of the carrier is had primarily through an operating shaft 7 supported in bearings in the main frame below the bed-plate l. The operating shaft is driven through the gearing connection 8, with a drive shaft 9, also mounted in bearings in the main frame, and in turn geared at 10, to a power shaft 11, mounted in mam frame bearings, and having a belt wheel 12 to be turned by a belt 13, driven from any power source, in this instance, a motor 14L.

Secured upon the shaft 3 is a disk 15, formed in the peripheral edge thereof, with a series of notches 16, the notches corresponding in number to the number of tables in the carrier. Mounted for independent rotary movement upon shaft 3, is an arm 17, the free end of which is connected, through appropriate connections, with one end of the rod 18, the opposite end of which is connected to the crank 19, arranged upon the relatively inner end of the operating shaft 7, so that in the operation of the shaft, a rotary reciprocatory movement is imparted to the arm. I For this purpose, there is secured on the under side of the bed-plate, a block 21, in

a which is slidably mounted 'a spring pressed locking dog 22, operative, when under the free influence of its spring, to engage anotch in said disk 15, and lock the disk, and thereby the table, for the operation of the mechanism for applying and fixing the extension edge section. Pivoted to the shaft 3, below the disk 15, is an arm 23, the free end of which is connected through rod 24: and lever 25, with a cam disk 26, secured upon the shaft 7. The lever 25 is pivoted at 25 to the table, and extends downwardly, the rod 24, being connected to the lower end, as at 24:, and said lever is provided with a pin or roller 27 to engage the groove of the cam 26. The arm 23 is extended beyond the shaft 3, as a release section 28, the outer or free edge of which is so arranged as to engage a projecting portion 29, or to be engaged by a projecting portion 30, of the respective dogs 22 and 20.

The cam 26 is so timed that, immediately following an operative movement of the carrier through the actuation of the arm 17, when locked to the disk, the-projection 30 of the dog 20, will engage the free end of the release section 28, to force said dog from engagement with a particular notch 16, thus freeing the arm from the disk, and permitting the crank to return the arm to an operative position, for a succeeding action, the angularity of the sides of the release section 28, and the do s, during the releasing operation, being suflicient to accomplish the result.

The locking dog 22 vwill, of course, engage the particular notch 16, alined therewith, as the carrier'stops, and following the operation of the placing mechanism, the cam 26 swings the arm 23 in a direction and to an extent to cause the release section 28 to engage the projection 29 of the locking dog 22, and force the dog to a release position, to free the carrier for further movement.

The feeder for the extension edge section is mounted on the frame and disposed so that in the rest periods of the carrier a table will be directly alined therewith radially of the table. The feeder comprises uprights 31 rising from the frame, in which is adjustably mounted the bin 32 for receiving the extension edge sections in superimposed relation, or in pile form. The bin 32 comprises side strips 33 of appropriate height,

relatively forward portions, or those portions normally underlying the edge-section in the bin, of slight width, being, in fact, just of sufficient size to support the section, while the forward portion of the bars are of greater'width, as at 37, and an increased height over the reduced width portion equal to the thickness of an extension edge section. The junctions of the respective sections of the follower bars present abrupt shoulders 37 to engage and push the lowermost section from the pile, the broader portions of the bars-supporting the pilemeanwhile.

The bin includes the adjustable forward walls 38, which may be readily moved to accommodate extension-edge sections of different widths, such Well being supported on rods 39, slid'ably mounted in bearings 40, and fixed in adjusted positions by set screws 41. The bearings are in turn arranged on rods 42, preferably two, the ends of which 1 pass loosely through openings in the guide arms, or extensions 44 thereof. The bin as a whole is adjustable to accommodate extension-edge sections of different lengths, through reversely threaded connections on shafts 45 and 46, passing respectively through extensions of the side walls and extensions of the guide arms. The shafts are connected for similar and simultaneous movement, as by chain and sprocket 47, and are adapted for manual operation, as the shaft 45 is provided with a hand wheel 48. Adjustment of the bin parts to accommodateextension-edge sections of different sizes is thusobviously provided for. A bearing block 49 is arranged at the rear portion of the bin, supported by the shaft 45 and other shafts to be mentioned, and slidably connected to the block, by a dovetailed connection, is a narrow strip 50, adjustable vertically through adjusting screw 51, such strip forming the rear wall of the bin, and servingto prevent rearward movement of other than the lowermost extension edge section from the bin.

A pastereceptac-le 52 is supported on the uprights 31 and directly below the bin. A past-er 53 is mounted for vertical movement in the receptacle and to a position to apply paste to the lowermost extension edge section of the pile. The paster is in the form of an open rectangular frame having depending side portions connected by pins 55 with rods 56, slidably mounted in guides 57 projecting from the side walls of the bin. The pins 55 are slidable on their bearings to permit movement in adjustment of the bin width as previously described. The pastor is preferably of the form shown to apply paste only in a rectangular line to the bot tom of the extension edge section, as this has been found suflicient for the purpose. However, the use of a paster of any form is contemplated.

The follower is reciprocated for feeding purposes, through a throw frame 58, including a shaft 59, on which is slidably mounted link 60, connected to the respective follower bars, the connection between the shaft 59 and links 60 permitting necessary movement in the size adjustment of the bin. The above frame is pivoted at 58 to the main frame, or extension thereof, and is operated through a rod 61, connected at its rear end to a lever 62, pivoted to the main frame, and having a roller 63, seating in a cam groove 64 of a cam 65, mounted on shaft 7.

The outer end of rod 61 has an adjustable connection with the arm or arms of the throw frame, including a pivotally mounted block 66, having an open jaw 67 to receive the arm' of the throw frame. One position of the jaw carries a spring 68 to bear on the throw frame arm, and the other portion has a set screw 69 to permit adjustment of the throw frame movement, in order that the followers may be moved with the necessary accuracy to exactly position the extension edge section on the box or cover. The paster is also timed and operated, through a shaft 70, mounted in the uprights 31 and also opening through the bearing block 49. This shaft 70 is connected by links with the rods 56, and is rotatably reciprocated to operate the paster, through an end link or arm 71 secured to the shaft and to the upper end of a rod 72, secured at its lower end to one end of lever 73, the opposite end of which is connected to the main frame. The lever 7 3 carries a roller 74 operative in a cam groove 75 of a cam wheel 76 secured on shaft 7.

The feeder thus, in properly timed sequence, pastes the lowermost extension-edge section of the pile in the bin, carries such pasted section from beneath the pile, and deposits it upon the exposed surface of the box or cover upon the particular table held in alinement with the feeder, through the described intermittent movement of the carrier.

Following the application of the extension-edge section to the box or cover, an initial press operates to fix the section in place on the box or cover. This press, in the form of a plate 77, substantially equal to the sur face area of the box or cover, is spring supported on rods 78, which pass through arms 79, pivotally mounted on the uprights 31, and connected, for vertically reciprocating the press, to a rod 80, connected in turn to a lever 81, pivotally supported at one end to the frame, and having a roller 82, operating in a cam groove 83, in a cam-wheel 84 secured on shaft 7. The press is thus turned to force the extension-edge section in place on the box or cover, after the same has been carried thereto by the follower.

The press 77 is preferably provided with an adjustable edge guide 85, depending from the inner edge thereof, and which in the maximum upper position of the press does not rise above the surface of the box or cover. This guide limits the innermost position of the extension-edge section when being delivered by the follower, and through its adjustment may be utilized to accurately position the section to provide an equal ec ge projection thereof beyond the box or cover. The press 77 also carries a spring-finger 86 (Fig. 1), so positioned that its free terminal rides over the box or cover on the table being advanced to the feeder, with the effect to properly seat such box or cover on the table. 4

A final press is employed to apply a heavy afiixing pressure to the extension-edge section and box, and this press is preferably of rest immediately succeeding the feeding operation, that is, the next step. The final press comprises a comparatively heavy plate 87, carried by a standard 88 slidably mounted in a bearing 89 rising above and extending below the bed-plate 1, the standard having a foot 90. An operating toggle 91 1s connected to the bed-plate and to a rod 92, passing through the foot and provided below the same with nut 93. The rod 92 has a collar 94 thereon, and on the rod between the collar and the bottom of a recess 95 formed in the foot about the rod, is arranged a stiff coil spring 96. The toggle is operated in both directions through a yoke 97, connected to the joint of the toggle by a link 98, and having opposed cam rollers 99, 100, enga ing respectively cams 101, 102, on shaft 7. The final press is designed to exert the final pressure during practically the entire period of rest of the particular table, following which, at a succeeding period of rest, the box or cover, with the extension-edge section applied thereto, may be removed from the table by hand.

It sometimes occurs, in the operation of the machine, that the box, or cover, adheres to the press when the latter is raised at the end of the pressing operation. In order to secure the detachment of the box, or cover, from the press in this event, stripping pins 103 are provided. These pins, two being shown, are stationarily supported on arms 10%, attached to the frame of the machine, and extend through the press plate 87 and said press plate is adapted to reciprocate about said stationary pins.

When the press plate 87 is at the lowest part of its stroke and in engagement with the box, or cover, the length of the pins 103 is such that the ends thereof are above the face of the said plate 87, and are, therefore, not in engagement with the box. When, however, the press plate returns to its initial position, the face of said plate is raised above the ends of said pins, and an adhering box or cover is brought in contact with said pins. As the pins are stationary and there fore hold the box against further upward movement, the continued upward movement of the press plate causes the detachment of the box or cover, and the box falls to the table beneath, from which it may be removed.

The machine, fed by hand or otherwise, receives a box or cover on each table, and applies and affixes an extension-edge section thereto, the positioning of the extension-edge section on the box or cover positively and accurately constituting one of the essentlal features of the invention. I
